Iraqi Lieutenant General Abdul-Wahab al-Saadi (2R) inspects the government forces unit on the outskirts of the northern city of Tikrit as they prepare to launch a military operation to take control of the city from Islamic State (IS) group fighters on March 10, 2015. Some 30,000 Iraqi soldiers, police and the increasingly influential paramilitary Popular Mobilisation units, which are dominated by Shiite militias, have been involved in a week-old operation to recapture Tikrit, one of the jihadists' main hubs since they overran large parts of Iraq nine months ago.
